plant native to subtropical wetlands on the East Coast of the United States. It catches its prey—chiefly insects and arachnids— with a trapping structure formed by the terminal portion of each of the plant's leaves and is

triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves

contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first

strike. The requirement of redundant triggering in this mechanism serves as a safeguard against
